Unforgiven Project

it looks like your progressing well, and so far everythings falling in place within spec.
 
Thank you Grumpy.. I have been searching the site to find where you recommended where the rotational force should fall into using the
beam wrench. I am having a hard time finding it. Do you remember off hand if my 28lbs is satisfactory?
 
Ok Thank you.. I did find this :

if your engine requires over about 30 ft lbs to get it started rotating or over about 25 ft lbs to keep it rotating youve got issues that you need to look into before further assembly

It had me slightly concerned but I was going to recheck the forces using and comparing to anther beam wrench.
 
that was for SBC, big blocks generally require 2-5 lbs more effort,
but thats not a major concern, as the resistance,
will be reduced rapidly as parts like rings lap and seat,
your within normal tolerance's
Ive seen guys trying to rotate an engine see 50 plus ft lbs required
,and its usually related to the wrong bearing clearances or file & fit rings installed,
right out of the package, but never checked for ring end gaps.

thank you I went back and tried to make that clearer/easier to understand

I'm not sure on which gasket would be better for this motor.. I has a 4.040 bore with aluminum heads.
I have it narrowed down to this gasket but I'm not sure of the bore size on the gasket.. One has a 4.100 I.D.
and the other has a 4.060 I.D. I was thinking since the block is bran new and the bores have been bored in the precise location,
It would be better to go with this gasket in with a 4.060 I.D

What are your thoughts?

head gaskets should be larger than the bore but minimally larger, having much larger head gaskets,
allow a shelf that can collect carbon and ash and might cause detonation issues in rare conditions
4.060 bore head gasket on a 4.040 bore is fine

I had to remove a slight amount of the head gasket in some areas to keep it from extending into
the bore and my gasket was .030 bigger. That's only .015 inches per side. You have done a more
accurate job of locating the bores than my engine, so hopefully you will not have a problem.

Since the copper was stamped, it left a sharp edge on one side. I did some bur removal and polishing.

I called Ryan and asked him to verifiy how he picked up the bores in relation to the locating dowels on the deck.. He said he just picked up the bore
on #1 and proceeded from there.
With only .010 per side of the bore, I thought that it would be safer to go with the 4.100 gaskets. That will give me .030 per side for a little wiggle room
just in case the dowels are out of location abit.
 
Do be aware of where you put those magnets, I got mine a little too close the lifters and every
time I try to install a push rod the magnet snatches the push rod.

1/8" metal hardware cloth and high heat magnets are good for catching crap like valve keepers or broken rocker parts

keep in mind all that metallic trash, cycles through the oil pump BEFORE it reaches the oil filter

magnets are ceramic and glass hard, don,t try to drill or grind them, as they can shatter


proper magnets trap metallic debris

How do the younger guys say it... "OH SNAP!!" LOL
That would suck for sure!

I was eyeing up a deep fry fish cooker pan to make use of a screen over the oil holes...
 
The engine is going together GREAT. It's almost like you did some planning ahead. :thumbsup: I hope it continues that way.
 
My new M77 oil pump came with a package containing another Blue spring.

The Instructions say " To Repair Original Equipment H/P corvette Oil Pumps #3876868 & #3904826 Use Enclosed BLUE Spring.

Does this make the pump a high pressure pump? I do not think I would want high pressure . Any thoughts?
 
there are oil pump testers available commercially or if your mechanically inclined you can fabricate one with reasonable care, after a bit of measuring and purchasing a gauge,
if you don,t test your never going to be sure what the oil pump is doing
